Officially this is an "authorized biography," by longtime Beatle hagiographer Barry Miles. But that's just a front, because the book really exists as a vehicle for McCartney to tell his story in his own words. Some fans were understandably put off by the way he squabbles over credits, even breaking down songwriting credits by percentages. (To pick one controversial example, he calculates "Norwegian Wood" as 40 percent his and 60 percent John's.) But on the page, as well as in song, his voice overflows with wit and affection. And he did less to fuck up his good luck than any rock star who ever existed, which might be why his memories make such marvelous company.
